    Simple problem just can't seem to get it

    How do you get the sum of all numbers that are less than a max value and either even or odd? I know that I am not supposed to ask to have assignments done for me but this is not the whole program i just need the basic idea of how to get all of the even or odd numbers up to that certain number. I am sorry if this question isn't clear.

    As this is homework, I wrote an example in c++ rather then c

    Code:
    #include <iostream>
    
    int main()
    {
    	int MAX = 7;
    	bool evens = false;
    	int sum = 0;
    	int i = 1;
    	if (evens)
    		i++;
    	for (; i <= MAX; i=i+2)
    		sum += i;
    	std::cout << sum;
    }
    Notes
    How do you get the sum of all numbers that are less than a max value and either even or odd?
    The sum is infinite, likewise the sum of all integers is also infinite. You are interested in whole numbers.

    And I encourage you to not do this using brute force (the way I showed). There is a much more elegant way involving the averages of a set of numbers [Guass did this]

    Code:
    if( x < y )
        if odd
            add to this sum
        else
            add to that sum
    If I understand what you're saying that is.
